Trivia: Enjoyed a good relationship with the Celtic support in his time as a player at the club and was often referred to as “Dolph” or “Big Dolph” given his perceived resemblance to his countryman, actor Dolph Lundgren. On 25 March 2010, it was announced that Mjällby would assume the role of assistant manager at Celtic, alongside temporary boss, and former team-mate, Neil Lennon.
Johan Mjallby: “For me he’s done a great job in his first year in charge. He’s shown he’s capable of becoming a very good manager. It would be a shame if he didn’t continue being a manager, but I’m quite sure he’s raring to go on and continue in this profession.”
“I don’t know why some people don’t like Neil. You’re asking the wrong person, because I like the man. We work well together and we’ve been good friends for a long time. He’s a fighter and a winner in all areas of life. That seems to upset some people.
“Is it a football problem or a society problem? It’s probably a bit of both. It’s a shame people seem to get so annoyed with Neil and with the person that he is. That shouldn’t happen. Even if you just don’t like Celtic, it’s ridiculous to put all of this on the manager. In a strange way it seems people are mixing football and the outside world too much.”
